Solar Orbiter observations of solar energetic electron events associated with hard microflares
Diane Mittaine, Andrea Francesco Battaglia, Laura RodrÃguez-GarcÃa +4
Generally, large solar flares accelerate electrons to high energies more efficiently than microflares. However, some microflares, known as hard microflares (HMFs), also produce hig…

The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
James McKevitt, Louise Harra, Gherardo Valori +13
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…

Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
